Doctors have voted in favour of calling on the Government to scrap its plans for overhauling the NHS.

Health Secretary Andrew Lansley is coming under increasing pressure over his reforms, which would see more than 150 organisations abolished and 80% of the NHS budget pass into the hands of GPs.

Some doctors support the content of the Health and Social Care Bill, currently going through Parliament, but many have been voicing opposition to parts of it, including increasing the role of private companies in delivering healthcare.

The British Medical Association (BMA) held an emergency meeting on Tuesday attended by almost 400 doctors to debate the plans.

Doctors voted in favour of calling on Mr Lansley to withdraw the Bill entirely and for a "halt to the proposed top-down reorganisation of the NHS". They said the Government should accept there was "no electoral mandate" for the plans which were not part of the election manifesto of either the Conservatives or the Liberal Democrats.

The meeting came after Liberal Democrat delegates rejected the shake-up at the party's spring conference, with members voting not to support the "damaging and unjustified" reforms.

Doctors also accused Mr Lansley of using "inaccurate and misleading information to denigrate the NHS", by comparing UK cancer and heart disease rates with those in Europe. They also voted for the Government to recognise that primary care trusts (PCTs), which face abolition, are currently losing staff and risk collapse, and for the Government not to undermine their current functions.

Addressing the meeting, BMA chairman Dr Hamish Meldrum said the Government's reforms could have "irreversible consequences" and would damage patient care.

Meanwhile, Labour tabled amendments to the Bill, designed to protect the NHS against the introduction of a full-blown competitive market, which the party warned would undermine care, increase bureaucracy and put the future of hospitals at risk.

Shadow health secretary John Healey said the amendments would strike out proposals to allow healthcare regulator Monitor to apply the full force of competition law to NHS contracts.
